Filter by:A problem with breathing during sleep, called obstructive sleep apnea (OSA), likely increases the risk of stroke and is common in people who have had a stroke, present in about 2/3 of stroke survivors. There is also evidence that OSA predicts worse outcome after stroke. The question being addressed in the Stroke and CPAP Outcome Study 3 (SCOUTS3) is how to improve use of continuous positive airway pressure (CPAP) therapy to treat OSA when started during intensive stroke rehabilitation.
Interruption of blood supply to the brain from a blocked blood vessel causes ischaemic stroke. This leads to symptoms relating to the areas of brain affected. For example, people with stroke may suddenly have trouble moving their arms, legs or face, and may find it hard to speak or lose consciousness. There are treatments available to open up the blocked blood vessel: - Thrombolysis involves injecting a medicine to break down the blood clot causing the blockage. - Thrombectomy means pulling the blood clot out through a tiny tube placed within the blood vessel. Both treatments can help restore blood supply to the brain and reverse the symptoms caused by stroke. These treatments are usually only offered when there is a clear onset time for stroke symptoms. However, for around 20% of strokes, the time of onset is unknown. Patients may wake up with symptoms, be confused or be found collapsed. So that treatment can be available to more people, the investigators have developed a method to estimate when an ischaemic stroke began, the CT Clock Tool. This method involves taking measurements from the brain imaging that most patients with stroke routinely get on arrival at hospital (CT or CAT scanning). In other words, no extra tests are needed to use the method; the investigators seek to make better use of existing tests. In this study, the aim is to understand whether it is feasible to use the CT Clock Tool method in the real world. For example, can doctors correctly use the tool during their normal work to produce accurate estimates for the onset time of stroke? The results of this study will be used to plan a future clinical trial for testing the safety of the CT Clock Tool when it is used to treat patients.
This is a prospective, multi-center, randomized effectiveness trial of the CardioGard Embolic Protection Cannula in high-risk valve surgery patients.
Non-Contrast Computed Tomography (NCCT) of the head is the most common imaging method used to assess patients attending the Emergency Department (ED) with a wide range of significant neurological presentations including trauma, stroke, seizure and reduced consciousness. Rapid review of the images supports clinical decision-making including treatment and onward referral. Radiologists, those reporting scans, often have significant backlogs and are unable to prioritise abnormal images of patients with time critical abnormalities. Similarly, identification of normal scans would support patient turnover in ED with significant waits and pressure on resources. To address this problem, Qure.AI has worked to develop the market approved qER algorithm, which is a software program that can analyse CT head to identify presence of abnormalities supporting workflow prioritisation. This study will trial the software in 4 NHS hospitals across the UK to evaluate the ability of the software to reduce the turnaround time of reporting scans with abnormalities that need to be prioritised.
The purpose of this pilot trial is to investigate the feasibility, safety, and efficacy of sodium valproate in patients with acute ischemic stroke, and also explore the mechanism: whether valproate increases peripheral anti-inflammatory CD177+ neutrophil levels.
The goal of this research project is to develop a tele-rehabilitation programme, which will constitute an original care pathway for brain damaged patients. It will aim to improve their impairments, activities and social participation. The programme will deliver a therapeutic education and self-education programme targeting the upper and lower limbs, and will assess the patients by means of a diary and self-evaluation questionnaires.
Identify the factors associated with a favorable clinical outcome in participants with acute ischemic stroke and large core infarcts within 24 hours of onset who are treated with endovascular intervention.
The objective of this study was to evaluate the safety and efficacy of early submaximal balloon angioplasty combined with medical therapy vs medical therapy alone for minor stroke/transient ischemic attack with intracranial atherosclerosis etiology.
For stroke patients, early initiation of therapy typically yields the best functional outcomes. Rehabilitation of stroke patients immediately after hospitalization minimizes deleterious effects of immobility and facilitates restoration of function. The investigators are testing if coordinated efforts between the medical and rehabilitation disciplines may improve stroke patient's functional recovery and subsequent follow-ups after discharge.
The effect of head position as a nonpharmacological therapy on acute ischemic stroke (AIS) remains inconclusive. Recent HOPES2 (Head dOwn-Position for acutE moderate ischemic Stroke with large artery atherosclerosis) suggest the safety, feasibility, and potential benefit of the head-down position (HDP) in acute ischemic stroke. The current study aims to investigate the efficacy and safety of HDP in acute moderate ischemic stroke patients with large artery atherosclerosis.
